I desperately need help on the transmission issue. Can anyone help me with info on how to shim the input shaft after the new clean roller bearings are installed to replace the tapered roller bearings that failed. Rear bearing was toast and front bearing had excessive play. It is an M94 box, splines, forks, & other bearings are good. My intent is to replace the input shaft bearings and all four seals.

I have a little experience with transmissions; having rebuilt ones from 40ÔÇÖs & 50ÔÇÖs cars in my younger days. But nothing was that precise back then. I donÔÇÖt have a dial indicator gauge, but I can get one at Harbor Frt. I do have a basic understanding of how to use one.

I have searched several forums, but I cannot find any instructions for how to measure the end play or preload on the shafts. Primary concern is with the input shaft since the rest of the bearings appear to be fine.
